I did already read the ast_read function, but there's nothing that free 
the channel. This is the code where the channel goes when it is ZOMBIE. 
So the ast_read returns NULL and the channel is still there. It should 
be safe to add ast_channelfree(chan); before exiting the function

    /* Stop if we're a zombie or need a soft hangup */
    if (ast_test_flag(chan, AST_FLAG_ZOMBIE) || ast_check_hangup(chan)) {
        if (chan->generator)
            ast_deactivate_generator(chan);
        ast_mutex_unlock(&chan->lock);
        return NULL;
    }
